Adult Health Nursing First Chapter Quizlet

Correct Answer: C

Rationale: The first action the nurse should take when a patient post-thyroidectomy develops signs of hypocalcemia is to assess the patient's calcium level. By assessing the patient's calcium level through laboratory testing, the nurse can confirm the presence of hypocalcemia and determine the severity of the condition. This information will guide further interventions, such as administering calcium supplements or notifying the healthcare provider for additional management. It is important to confirm the diagnosis before proceeding with treatment to ensure appropriate and safe care for the patient.

Correct Answer: D

Rationale: A hard mass and a reddened area on one breast are key clinical signs that confirm the diagnosis of mastitis. Mastitis is an infection of the breast tissue that often presents with localized redness, warmth, and swelling of the breast. The presence of a hard mass along with the other symptoms suggests inflammation and infection within the breast tissue. In contrast, the other findings such as enlarged glands in the axilla, normal temperature, and engorged breasts are not specific findings for mastitis and may be present in other conditions. Therefore, the presence of a hard mass and reddened area on one breast is the additional finding that strongly confirms the diagnosis of mastitis in this case.

Correct Answer: A

Rationale: Hashimoto's thyroiditis is an autoimmune disorder characterized by chronic inflammation of the thyroid gland. In this condition, lymphocytic infiltration and germinal centers can be seen in the thyroid tissue. This inflammation can lead to the formation of thyroid nodules and enlargement of the thyroid gland, causing symptoms such as difficulty swallowing and breathing due to compression of surrounding structures. Additionally, Hashimoto's thyroiditis can result in hypothyroidism over time, further contributing to the symptoms. Therefore, the patient in this case is most likely experiencing these symptoms due to Hashimoto's thyroiditis. Graves' disease, on the other hand, typically presents with hyperthyroidism and is less likely to manifest as compressive symptoms of the thyroid gland.

Correct Answer: B

Rationale: T cell exhaustion is a state of T cell dysfunction that arises during chronic viral infections or cancer. In the case of a chronic viral infection, the persistent exposure to viral antigens leads to continuous stimulation of CD8+ cytotoxic T cells. Over time, this sustained stimulation can lead to T cell exhaustion, characterized by the upregulation of inhibitory receptors, impaired effector functions, and reduced proliferative capacity. As a result, despite the elevated levels of CD8+ T cells in the blood, their function may be compromised, ultimately impacting the immune response against the viral infection. In contrast, activation-induced cell death (AICD) may contribute to T cell loss during chronic infections but would not explain the persistently elevated CD8+ T cell levels. Thymic involution refers to the age-related decline in thymus function, which is not directly related to the observed increase in CD8+ T cells. Antigenic

Correct Answer: C

Rationale: Incident Reports (IRs) must be summarized monthly and stored in a secured cabinet for several reasons. Firstly, summarizing the IRs monthly allows for a consolidated overview of the incidents that have occurred, highlighting any recurring patterns or trends that may need to be addressed. By storing the summarized IRs in a secured cabinet, the information is kept confidential and protected from unauthorized access. This practice also ensures that the reports are organized and easily accessible for future reference or audits. Storing the IRs on an open cabinet, table top, or with a classification system that may not be easily understandable can lead to potential breaches of confidentiality or difficulty in retrieving and understanding the information when needed.
